This invention relates to a line indicating device adapted to facilitate comparison or computation of various data noted on a plurality of loose sheets mounted on any suitable retaining '5 means. Although the invention is particularly described in connection with a loose leaf binder it will be obvious that it may be applied with equal advantage to any summary board or platform having any suitable means forretaining loose sheets in position with corresponding portions of a plurality of sheets in exposed position. It is an object of thisinvention to provide a loose leaf hinder or summary board with a line indicating device that may be readily detached therefrom and applied to another binder or board. It isv a further object of this invention to provide improved means for adjusting the angularity of the line guide and maintaining the line guide in proper position to facilitate reading of data from the sheets regardless of the total thickness of the sheets mounted in, the binder or on the board. Other objects of this inven-. tion willbecome apparent upon reading the following description taken in conjunction with the accompanying drawings, in which:

Figure 1 is a perspective. view of a loose leaf binder embodying the invention;

Figure 2 is adetail View, partly in section and partly in elevation, of the line indicating device;

Figure 3 is a detail plan view of the line indicating device;

Figure 4 is a sectional view taken along the line IV-IV of Figure 3; and

Figure 5 is a sectional view taken along the line VV of Figure 3. i i

In the drawings the reference numerals 2 and 3 indicate a pair of covermembers hingedly connected to opposite edges of a back section 4, as indicated at 5 and 6, respectively, Figure l. A conventional ring metal I carrying a plurality of divided rings 8 is secured to the back section 4 by any suitable means. The ring metal 1 is preferably provided at each end with a trigger 9 operable to open and close the divided rings 8. A plurality of sheets I0, each shorter than the binder, is arranged on the divided rings 8 in overlapping relationship with corresponding portions of each sheet exposed for reference. Although only one bank of sheets is shown, it will be understood that the ring metal is capable of holding several banks of sheets with any bank exposed for reference. A pair of sheet lifters l l is carried on the divided rings 8 adjacent each of the covers 2 and 3 so that one pair of sheet lifters is under the sheets l0 regardless of the position of the sheets. If desired, a single sheet lifter extending the length of the binder may be substituted for each pair of sheet lifters I I. 'Ihe sheet lifters each have one edge l2 extending at H anangle to'the rest of the lifterto act as an align- "5 ing member to keep the sheets Ill in orderly ar ran'gement so that each sheet is parallel to every other sheet. The sheet lifters are preferably formed of fiber and perform the usual function of facilitating movement of the sheets from one side of the binder to the other.

The cover members 2 and 3 are each provided with a short strap l3 secured thereto in any suitable manner. {I'hestraps l3 are provided at their free ends with a snap fastener l4 so that the 15 straps may be effective to hold the loose leaf binder in standing position with the desired sheets exposed, as indicated in Figure 1.

Ahinge plate l5 is permanently secured to the cover member 2 by means of rivets IE or in any 30 other suitable manner. The hinge plate is provided with a plurality of spaced hinge lugs IT. The line indicating device includes a hinge plate l8 provided with a plurality of hinge lugs l9 adapted to fit in between the hinge lugs H. A 55 hinge pintle 20 is adapted to pass through the hinge lugs l1 and 19 to secure the line indicating device to the binder. The hinge pintle 20 is provided with a bent end 2| which acts as a finger piece to facilitate the rapid removal of the line indicating device from the binder so that it may be readily secured to any other hinder or board provided with a hinge plate similar to the hinge plate IS.

The hinge plate I8 is provided with a pair of a curled extensions 22. A rod 23 has its opposite ends mounted in the extensions 22. The rod is circular in cross-section and may be secured against displacement from said extensions in any suitable manner. '40

A line guide support 24 is slidably and rotatably mounted on the rod 23. The line guide support includes a housing 25 and a spacer block 26 extending only a portion of the length of the housing. The spacer block 26 is provided with a 5 recess 21 (Figure 4) in which a round headed plunger 28 is positioned. The head of the plunger 28 is of substantially the same diameter as the recess 21 and a coiled spring 29 exerts force against the plunger head to maintain it in con- 50 tact with the rod 23. The housing 25 is provided with an aperture 30 to facilitate assembly of the plunger 28 in the recess. The end of the plunger is peened over, as indicated at 3|, to prevent the plunger from being lost when the rod 23 is not 55 secure the line guide to the bell-crank 34.

in the housing. The plunger cooperates with the housing 25 to maintain a frictional contact with the rod 23 sufiicient to hold the housing in any position on the rod and not tight enough to interfere with intentional sliding or rotative movement of the housing.

Opposite walls of the housing are bent outwardly adjacent the end of the spacer block to form a pair of flat ears 32. A flat plate member 33 is Welded or riveted to the ears 32. A bellcrank 34 is pivoted to the plate member 33, as indicated at 35. The arm 36 of the bell-crank is provided with an upturned flange 31. A stud 38 passes through the flange 3! and is secured to the housing 25. A coiled spring 39 encircles the stud 38 and exerts force against the flange 31 to urge it towards the housing 25. a

A screw 40 threaded through the housing'25 and the spacer block 26 engages the flange 31 and when rotated in one direction forces the flange against the action of the spring 39 to move the arm 4| of the bell-crank downwardly. When the screw 411 is rotated in the opposite direction the spring 39 acts against the flange 31 to move the arm 4.! upwardly. The bell crank arm 4| is provided with a pair of spaced studs 42. A line uide 43 is provided with a pair of pear-shaped apertures 44 adapted to engage the studs 42 to The line guide could be permanently secured to the bell-crank but the detachable securement is preferred because of the ease with which a line guide may be replaced if it becomes bent. A clamp 45 (Figure 1) may be provided on the cover 2 to secure the free end of the line guide when the device is not being used.

When only a few banks of sheets are mounted on the rings 8 it is obvious that the line guide will lie close to the sheets and data on the sheets may be easily read. When many banks of sheets are mounted on the rings the hinge 20 permits pivoting of the plate I8 to bring the rod 23 to the proper height so that the line guide may still be parallel to the top surface of the sheets. The parallelism between the reading edge of the line guide and the horizontal rows of data on the sheets I!) is maintained by the screw 43 and the spring 39.

Although we have described a preferred embodiment of our invention in considerable detail, it will be understood that the description thereof is illustrative, rather than restrictive, as many details may be modified or changed without departing from the spirit or scope of our invention. Accordingly, we do not desire to be restricted to the exact construction described, except as limited by the appended claims.
